Cython 1

Use your knowledge of Cython to convert the program you wrote in Assignment 3 into a Cython program. Pay particular attention to the following:

Place the resulting code in a file called nbody_cython.pyx.

Cython provides a module called pyximport for importing .pyx files directly. This module will load and compile the Cython code automatically for you. Use the following commands from IPython or Jupyter in order to load the nbody_cython.pyx module:

%load_ext Cython
import pyximport

At this point you should be able to load your Cython program using the normal import statement:

import nbody_cython

When you are satisfied that your program is working, commit it to the same repository you used in Assignment 3
